Quite a few Fast Radio Bursts have dispersion measurements which are near multiples of a single value. The dispersion measurement shows how much the radio waves are spread out in frequency as they travel through space. The greater their distance, the greater the spreading. This would seem to suggest a couple of possibilities:

1.) That the FRB sources are located at even multiples of a given distance from Earth. or,

2.) That something affecting the frequency spreading is imposed on the emissions in even unit multiples.

A previous thread on FRBs, on this forum, provides further information.

In News/Arecibo I spoke of a 'Nature" article. At leas a summary is readable and open in "Nature" of January 11.
